The Huawei Back Up Box is used in a residential rooftop PV system to monitor the inverter in grid-connected or off-grid condition. When the grid fails, the inverter switches to the off-grid state and supplies power to off-grid loads in backup mode. When the grid recovers, the inverter switches back to the grid-connected state.
The Huawei Back Up Box works with the LG Chem HV, or with the new Huawei LUNA 2000 battery modules. The box features a 5kW backup power that is more than enough for essential loads.
